Hoba meteorite

The largest known meteorite (as a single piece), and the most massive naturally-occurring piece of iron known on Earth’s surface, left no crater. It’s the Hoba meteorite, lies on the farm “Hoba West”, not far from Grootfontein, in the Otjozondjupa Region of Namibia. The impact is thought to have occurred more recently than 80,000 years ago. The meteorite is unusual in that it is flat on both major surfaces, possibly causing it to have skipped across the top of the atmosphere like a flat stone skipping on water. Thus reducing its velocity and resulting in no crater. The meteor would have been slowed to about 720 miles per hour (0.32 km/s) from its speed on entering the Earth’s atmosphere, typically in excess of 10 km/s for similar object.
